Saturn-PIA08992.jpgSurging Across the Rings58 visiteCaption NASA:"A surge in brightness appears on the Rings directly opposite the Sun from the Cassini Spacecraft. This "opposition surge" travels across the Rings as the Spacecraft watches. This view looks toward the sunlit side of the Rings from about 9° below the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft wide-angle camera on June 12, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 853 nanometers.
The view was acquired at a distance of approx. 524.374 Km (such as about 325.830 miles) from Saturn.
Image scale is 31 Km (about 19 miles) per pixel".MareKromium

The_Rings-PIA08988.jpgBright Region in the C-Ring60 visiteCaption NASA:"This bright, isolated plateau in the middle of the C-Ring displays interesting internal variations in brightness. The plateau is not high in terms of elevation, but rather in terms of its particle density (seen here as brightness), which is several times higher than the surrounding Ring Structure.
Ring scientists are working to understand what produces the sharp boundaries of the plateau features, as well as the nature of the internal variations in brightness.
This view looks toward the sunlit side of the Rings from about 18° below the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 12, 2007 at a distance of approx. 230.000 Km (about 143.000 miles) from Saturn. Image scale is roughly 1 Km (3353 feet) per pixel".MareKromium

Saturn-PIA08987.jpgNorthern Latitudes58 visiteCaption NASA:"Incredible swirling details in Saturn's Northern Clouds can be seen in this dazzling view. Shadows cast by the Rings embrace the Northern Hemisphere.
The view looks toward the unilluminated side of the Rings from about 16° above the Ring-Plane.
The image was taken with the Cassini spacecraft wide-angle camera on June 10, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 939 nanometers. The view was acquired at a distance of approx. 1,3 MKM (such as about 800.000 miles) from Saturn. Image scale is roughly 72 Km (about 45 miles) per pixel".MareKromium

The_Rings-PIA08985.jpgMoons...58 visiteCaption NASA:"The effects of three of Saturn's Ring Moons can be spotted in this single narrow-angle camera view.
The image has been strongly enhanced to better show the wakes on both sides of the Encke Gap caused by Pan (left of center), as well as a hint of the edge waves in the narrow Keeler Gap caused by Daphnis (just below center).
Bright Prometheus (on the right) pulls away from its latest close encounter with the F-Ring. The aftereffects of its recent passes are visible in the Ring's inner edge.
This view looks toward the unilluminated side of the Rings from about 10° above the Ping-Plane.
Saturn's shadow cuts across the Rings at the top of the scene.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 5, 2007 at a distance of approx. 2,3 MKM (about 1,4 MMs) from Pan.
Image scale is about 13 Km (approx. 8 miles) per pixel".MareKromium

as12-53-7917-1.jpgAS 12-53-7917 - What are we looking at?!?62 visiteIl titolo di questo dettaglio ultra magnificato del bellissimo frame "Just like 2001" ci pare sufficientemente autoesplicativo: che cosa stiamo guardando, infatti?
Un semplice vizio dell'immagine occorso in sede di sviluppo della pellicola originale o durante la digitalizzazione?
O forse si tratta di pulviscolo atmosferico (o magari qualcosa di similare) che, rimasto intrappolato nelle ottiche della Hasselblad usata per ottenere la fotografia originale, ha poi prodotto questo (davvero!) bizzarro effetto sull'immagine una volta che essa è stata sviluppata?
Oppure stiamo guardando una "Creatura dello Spazio"?
Scherzi e provocazioni a parte, il dettaglio è suggestivo; la nostra razionalità ed il necessario pragmatismo ci dicono che si tratta di semplice pulviscolo o, comunque, di un image-artifact di un qualche tipo.
Ma la verità, come ben sapete, talvolta può largamente superare anche la più sfrenata immaginazione...MareKromium

SOL1239-2P236353641ESFAUATP2568L7M1.jpgFlat-Rock, after Spirit rolled over it (1)62 visiteUn frame davvero curioso: la roccia piatta (Flat-Rock) che potete vedere accanto all'area bianca è stata "rotta", a nostro avviso, dal MER Spirit il quale - passateci la battuta... - ci è allegramente "passato sopra", fratturandola.
Questo fatto, come ovvio, non prova nulla se non che la roccia Marziana che abbiamo battezzato "Flat-Rock" è fragile.
E come mai è fragile?
Forse perchè, internamente, è porosa. Ed è davvero un peccato che la definizione di questo frame sia tutt'altro che ottimale però, se operate un leggero ingrandimento del dettaglio e poi guardate bene, forse potreste scorgere alcuni particolari davvero MOLTO interessanti...MareKromium

AS14-68-9455_HR.jpgAS 14-68-9455 - Triple Core59 visite134:26:27 MT - While Ed worked on the triple core, Al was digging a trench and, in the end, needed the extension handle to get it to full depth. In this photo, we can see that the extension handle has been removed prior to Ed's second attempt at getting the triple. Because of the length of the triple core, Ed can hammer the first section or two into the ground without the extension handle.
He will need it, however, to finish the job and, in fact, gets it back from Al at about 134:27:48 MT.MareKromium
